Description

The present invention relates to decorative sheet material and, more particularly, to decorative material, which can be used, for example, for wall cladding or for coating furniture, etc.

Wood veneer or vinyl chloride sheets and the like have usually been used as such a decorative material, with the former was made by cutting natural wood into very thin sheets and has the disadvantage of being due to the recent lack of natural wood is available only to a limited extent, which at the same time reduces the dimensions and applications are limited and which also due to its material properties in use breaks easily. In the meantime, the latter has been through

For the binder for connecting the twisted yarns Y and the base material B, on the other hand, agents based on emulsions which form a film having a water resistance and a flexibility in the range of 10 to 50 C by heating and drying are desired. Although it is preferable to use a binder containing Iffl

Such a sheet-like decorative material can be effectively produced by a method according to the present invention Invention and as described below.

This method generally comprises the following steps; Continuous feeding in one direction of a large » Number of twisted yarns that are uniformly arranged in tight layers and in the direction, width and thickness of a web shape correspond. Simultaneous feeding of a web-shaped, flat, thin base material at the same speed and in the same direction as the twisted yarn, so that in a first position first on one side of the base material Applied binders and the subsequent depositing of the twisted yarns arranged in a band on this side of the base material with the binder causes the lower layers of the twisted yarns adjacent to one side of the base material on this side by drying the binder on the base

glue the material in place. This is followed by a rearrangement of the middle ones

and top layers of twisted yarn that are not attached to this

| Glue the 20 side of the base material, in a non-uniform layer ; structure "according to which all rearranged twisted yarns with a Second binding agent are provided and the twisted yarns are adhered to one another by subsequent drying of the binding agent.

Such a method makes it possible to adjust the dimensions of the base material, the number of twisted threads and the shape

layering as desired for continuous manufacture
of the sheet-like decoration material in an exceptionally effective manner and the method is particularly suitable for use in systems without warp beam devices, since the supply takes place via external warp beams on which

when a greater number of twisted yarns is previously uniform and tight ^; ; are wound with respect to width and thickness so that they are in the whole j.

The method for the production of the sheet-like decoration material is shown below with reference to FIGS. 3 »4, 5 and 6 in %

The method can largely be carried out in a first process according to the | Fig. 3 and a second process according to Fig. 5 are divided. $

As can be seen in Fig. 3, the base material B is on
a rotatable coil 10 wound while the twisted

After the binding agent 14 has dried in the manner described, the sheet-like decoration material BY, which consists of the twisted yarns Y and the base material B, is wound onto a spool 18 _{via the pulling rollers r ^ g, r ^ y, r 18 and r ^} wound, which is provided with Andrückwickelrcllen r _2Q and r ₂₁ to end the first manufacturing process.

The thus wound on the spool 18 sheet-like decorative material BY is then transferred to another coil 19 in order to _". The second production process according to Fig 5, which has to be subjected to a certain similarity with the one in Fig first process shown. 3 The material BY is withdrawn from the spool 19 and continuously fed to the binding agent roll r5b via the tensioning rollers rib, r2b, r3b and r4b. Corresponding brushes Fa and Fb are arranged on the outer surfaces of the tensioning roller r2b and the binding agent roller r5b in such a way that they twist the G _a touch rne Y of the decoration material bahnenjförmigen BY.

wherein the binding agent 14, which is located in the storage tank 13b attached to all twisted yarns Y to join them together. The sheet-like so provided with the binding agent 14 Decoration material BY is continuously fed through the Ansaui belt 12b over the flat drying plate 15b and through a Row of pull rollers r9b, r10b, r11b and r12b over a first drying drum D1b and then from the pulleys r13b, ri4b and r15b over

After the binding agent 14 has dried, the decorative material BY in the form of a sheet is wound up via the tension rollers ri6b, r17b, r18b -and r19b onto a reel 18b provided with pressure take-up rollers r20b and r21b to complete the second manufacturing process into a roll of finished decoration material P.

The sheet-like decoration material P, in which the twisted yarns are arranged in a non- uniformly layered structure on the base material (see FIG. 2), can be continuously produced as described above by the first and second production processes. Depending on the necessity, the sheet-like decoration material obtained in this way can be printed in a further work process (not shown) or provided with a coating for reinforcement.

It should be noted that although the foregoing embodiment has described first and second manufacturing processes with an arrangement as shown in FIGS. 3 and 5, the sheet-like decoration material is wound on a spool 18 (FIG. 3)
to be transferred to the spool 19 (Fig. 5), the
Method can be modified so that an arrangement according to

Similar to the method according to FIGS. 3 to 6, the method according to FIG. 7 also allows the dimensions of the Base material, the number of twisted yarns and the shapes of the layers as desired for continuous production of the sheet-like decoration material with high efficiency set and the method according to FIG. 7 is particularly for use in spinning mills and the like. Which with warp beams and Layer devices are provided, suitable.

In the arrangement of FIG. 7, the twisted yarns Y are drawn from a large number of cross-wound bobbins C 1, C ₂ , C 1, ... and Cn, which are attached to a bobbin frame C, and first pass through an ordinary sheet Em , which is right in front of the bobbin! frame C is arranged. The number of twisted yarns Y is, as in the embodiment according to FIGS. 3 to 6, from 4,000 to 12,000 and the twisted yarns Y, which are each passed between two associated needles of the sheet E ^, generally have the same number Twisted yarns Y passing through the ordinary sheet E * are subsequently passed through an accordion-like sheet E ₂ , which can be adjusted in its width as desired and which is positioned between the ordinary sheet E and the application rollers r6c, r7c and r8c for the in the Storage tank

described, the twisted yarns Y are brought into a non-uniformly layered structure by passing through the sheet E2, which as a whole forms a web shape. The twisted yarns Y which have passed through the sheet Έ, are completely provided with the binding agent 14 when they are passed between the rollers r6c and r7c, and r7c and r8c and are still fed to the rollers T ^ and r «* which are at a distance from the rollers r6c, r7c and r8c.

At a position between the rolls r8c and r ^ n ^unc * below the twisted yarns Y running therebetween, the base material B is arranged as a roll on the bobbin 10b, and the base material B is drawn off therefrom and the roll ro? It is fed at a speed equal to that of the twisted yarns Y. In this way, the twisted yarns Y provided with the binder 14 and the base material B on the reel ^? brought together so that they stick together. The web-like decoration material BY thus formed is then fed to a drying process (not shown here) which is similar to that according to FIG. 3 and, after the binding agent has dried, is wound onto a roll (not shown here).
